Question 3 On your auxiliary handout, draw this vascular bundle as it would be seen in longitudinal section. Make sure to label the xylem, phloem, and fiber cells – they should also be drawn so that they are discernible as their specific tissue layers (e.g. distinct cell shapes or prominent cell features are shown). You do not need to draw/label anything besides xylem, phloem, and fibers.
